Early life

Arno Karlen was born on May 7, 1937, in Philadelphia. His parents were Jewish immigrants from modern-day Belarus and Ukraine who immigrated to the United States in the early 1900s. He was a talented child who was promoted two grades and finished high school at 15. As a teenager, he was interested in literature, science, and classical music. He studied music, and graduated from Antioch College with majors in English and French literature.

Academic career

After he finished college, Karlen wrote for many magazines and spent a couple of years traveling around Europe writing about food and culture. Eventually, he became editor of several magazines, including Holiday and Newsweek, and published a short stories book called White Apples at the age of 24.

In the 1970s, Karlen became an Associate Professor in the English Department Writing Program at Penn State University. In the coming years he wrote books in fields of history, medicine, and science. He then returned to New York as executive editor of Penthouse Magazine and Physicians World magazines.^[4]

In the 1990s, Karlen achieved a doctorate in sexology while studying for three years at an institute of psychoanalysis. Karlen won the 1996 Rhone-Poulenc Prize for science books with Plague's Progress, but did not attend the award ceremony due to illness. In the ten years before his death, Karlen worked as a psychotherapist and kept writing articles and publishing books.

Personal life

Karlen had two children from his first marriage, which ended in divorce. He lived many years with his second wife in Greenwich Village, New York City, until his death. By the time of his death, he had six grandchildren. He was also a relative (first cousin, once removed) of the pianist Mischa Levitzki and was also a relative of Irving R. Levine.

On May 13, 2010, Karlen died from emphysema. He was still working until three months before his death as a therapist in private practice.
